You know there's another planetarium program that comes with edubuntu-
KStars . I haven't seen the one you mentioned.

I know what you mean tho about the linux--I downloaded my first distro
about a month ago. I'm on my 3rd so far-I'm hooked! Linux may be a bit
weird after windows, but I would gladly convert completely-if my Vaio
didn't run so darn good the way Sony tweaked it with XP (its about 3
times faster than my parents Dell with the same hardware).
